Another workaround is to create a script which periodically runs the db2 command: "db2diag -A" which creates an archive copy of the file to prevent the log growth. Then you need to move the archive copy of the log to a different directory because the kud agent not only parses the db2diag files (db2diag*.log) but also the other notify file (*.nfy) of DB2 in the same directory.
